'''Worker Proxy setup''' | |||
in /etc/rspamd/local.d/worker-proxy.inc | |||
# local.d/worker-proxy.inc | |||
milter = yes; # Enable milter mode | |||
timeout = 120s; # Needed for Milter usually | |||
upstream "local" { | |||
default = yes; # Self-scan upstreams are always default | |||
self_scan = yes; # Enable self-scan | |||
} | |||
count = 4; # Spawn more processes in self-scan mode | |||
max_retries = 5; # How many times master is queried in case of failure | |||
discard_on_reject = false; # Discard message instead of rejection | |||
quarantine_on_reject = false; # Tell MTA to quarantine rejected messages | |||
spam_header = "X-Spam"; # Use the specific spam header | |||
reject_message = "Spam message rejected"; # Use custom rejection message | |||
'''Disable DKIM Signing on rspamd''' | |||
To disable DKIM signing (i.e. you use OpenDKIM, or signing is done elsewhere- ie, that's our case) | |||
# local.d/dkim_signing.conf | |||
enabled = false; | |||
and restart rspamd service after that. | |||
'''Setting up the WebUI''' | |||
<br />For using the location, <webroot>/rspamd, | |||
<br />Add the following on /etc/mailman3/nginx.conf | |||
location /rspamd/ { | |||
proxy_pass http://localhost:11334/; | |||
proxy_set_header Host $host; | |||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; | |||
} | |||
Now, check nginx syntax, restart the nginx service and check the status. | |||
<br/> After restart, you can visit <webroot>/rspamd and login with the previously created password. | |||
<br /> | |||
'''Setting up rspamd Worker proxy config on postfix''' | |||
<br />Rspamd Worker proxy config | |||
<br />On /etc/postfix/main.cf | |||
Don't forget to disable existing configs for the same below | |||
## | |||
## Spam filter and DKIM signatures via Rspamd | |||
## | |||
smtpd_milters = inet:localhost:11332, local:/opendkim/opendkim.sock | |||
non_smtpd_milters = inet:localhost:11332, local:/opendkim/opendkim.sock | |||
milter_protocol = 6 | |||
milter_mail_macros = i {mail_addr} {client_addr} {client_name} {auth_authen} | |||
milter_default_action = accept | |||
and then restart postfix. | |||
Finally, enable rspamd service if everything seems to work properly | |||
<code>$ sudo systemctl enable rspamd</code>. | |||
